cult are quite durable wheels. try to not let your board go completely 90 degrees to the drop of the hill, keep it at a slight angle, that will help keep your wheels turning while sliding and should prevent flatspots from happening.

Do the wheels make a difference in stand up slides and ground slides? Coz every time I do stand-ups they seem to not be as smooth and responsive as when I do ground slides? I'm broke so my friend gave me these gunslingers. I just want to know is it my technique more than anything else or do the wheels matter?
